Anthesterion

It appeared suddenly to Amamiya Yuuhi during his date with Hiwatari. It was shown in this encounter that Golems do not attack civilians.

Yuuhi quickly made an excuse to get out of the date and ran to draw the golem's attention away from the town in order to fight it.

After exhausting himself by running around and using his domain control to evade the golem's attacks, he was cornered in the river bank and was about to die when the Princess saved him by throwing a car at the golem, which was easily deflected. However, the golem was defeated by a following roundhouse kick delivered by the Princess after jumping the whole river from the other side.
